` This invention relates to a simple and easily manipulated device for shakingor throwing dice within a casing provided witha transparent top through which the dice are visible, and it is hereinafter fully described and claimed, and illustrated .in the accompanying drawing, wherein:

Figure 1, is a sectional view takenv on la. plane extending verticallyxand' centrally through the dice shaking or throwing device,

Figure 2 isa sectional View taken Lon the horizontal planes indicatedV by thefline 2,-2 of Figure 1. y h

The devicecomprises a casing lwhic'h is of cylindrical formation .and consists of Va lower section or body -2 and an upper section or cover 3. The cover 3 is removabl secured to the body 2, and is provided witi a transparent top or upper wall 4 through which the dice 5 are visible. Lower and upper frame pieces 6 and 7, respectively, are arranged in relatively spaced relation within the casing 1. A vertical shaft 8 is journaled in bearings 9 formed in the frame pieces 6 and 7, and its upper end extends above the frame piece 7. A turn table 1() upon which the dice 5 rest, is fixed at its center to the upper end of the shaft. 8. A vertical shaft 11 located between the frame pieces 6 and 7, is joiirnaled in bearings 12 formed in said pieces, and has secured thereto a disk 13. A ring gear 14 is loosely mounted upon the disk 13, and meshes with a pinion 15 fixed to the shaft 8 between the frame pieces 6 and 7. The ring gear 14 is provided with a conical plate 16 which overlies the disk 13 and contacts with the under side of the frame piece 7 and is provided with an opening 17 for the reception of the shaft 11. Clutch rollers 18 which are mounted in recesses 19 formed in the disk 13 and opening out through the edge thereof, function when the shaft 1 1 is rotated in one direction to lock the ring gear 14 to the disk. i The clutch rollers 18 open ate to release the ring gear 14 from its connection with the disk 13 when the shaft 11 is rotated in the opposite direction. A sector gear 2O is pivoted to and between the frame pieces 6 and 7 by a shaft 21 which is journaled in bearings 22 formed in. said pieces. rlhe sector gear 2O meshes with a pinion 23 fixed to the shaft 11, and 1s provided with a manipulating or thumb Apiece 24`which extendsthrough an opening25 :in the lateral side of the body 2. -The shafts 11 and 21 are located at opposite sides of the shaft 8, andthejsector gear 20 `is providecl-;\vith a slot 26 forthe reception of the shaft 8. A pin 27 'on the framepiece 6 and a shoulder- 28 on the-sector gear 20, cooperate to limit theymovement of this gear in one direction.` A coil spring K29secured at one end to alpinfBO on thev frame piecepand at its other endto a-pin 31 on they thumb piece- 24,.norma1ly\holds the sectorgear 2O with its shoulde'ri28 in contactfwith the stop pin 27 f The rmovement of the ysector gear 20 in the opposite direction `is limited byone of the end i walls 'ofthe opening- 25 with which ththun'ib-piece 24 `cooperates to attain this en In practice, the device may be held in one of the hands and operated by the thumb of the hand in which it is supported, and to effect the operation thereof the sector gear 20 is moved through the medium of the thumb piece 24 in the direction indicated by the arrow of Figure 2. When the sector gear 20 is moved in this direction, the

spring 29 is tensioned, and the shaft 11 isV moved in a direction to cause the clutch rollers 18 to lock the ring gear 14 to the disk 13. As the ring gear 14 meshes with the pinion 15, the shaft 8 and turn table 10 will be rotated,lwith the result that the dice 5 will be shaken or thrown about the casing 1 upon the turn table. To insure that the proper shaking or throwing movement will be imparted to the dice 5, a game cloth 32' u is secured to the upper side of the turn table 10. When the thumb piece 24 is re-V leased, the spring 29 will return the sector gear 20 to its normal position, in which position of said part its shoulder 28 contacts with the stop pin 27. This movement of the sector gear 20 will not impart movement to the turn table 10, due to thefact that the shaft 11 is rotated, during this movement of the sector gear, ina direction to cause the brake rollers 18 to free the ring gear 14 from its engagement with the disk 13.

It should be understood that the drawing is merely illustrative and does not pretend to give exact proportions. Furthermore, the said drawing is illustrative of a preferred construction, it being my expectation that various changes and modifications may be made without departing from the spirit and scope of my invention.

that is claimed is 1. A dice shaking or throwing device comprising a casing having a transparent top, a table rotatably supported wit-hin the casing and upon which the dice rest, a pinion fixed to the table, a disk rotatably supported within the casing, a gear loosely mounted on the disk and meshing with the pinion, means adapted to lock the gear to the disk when the latter is rotated in one direction, a pinion fixed to the disk, and a manually operable sector gear pivoted within the casing and meshing with the pinion fixed to the disk.

2. A dice shaking or throwing device comprising a casing having a transparent top, a table rotatably supported within the oasing and upon which the dice rest, a pinion fixed to the table, a disk rotatably supported within the casing, a ring gear loosely mounted 0n the disk and meshing with the pinion, means adapted to lock the gear to the disk when the latter is rotated in one direction, a pinion fixed to the disk, a manually operable sector gear meshing With the pinion fixed to the disk, and a spring secured to the casing and sector gear.

3. A dice shaking or throwing device comprising a easing having a transparent top and an opening in its side, a shaft rotatably supported within the casing, a table secured to the upper end of the shaft and upon which the dice rest, a pinion fixed to the shaft below the table, a second shaft rotatably supported within the casing below the table and provided with a disk having recesses opening out through the edge thereof, brake rollers mounted in said recesses of the disk, a ring gear surrounding the edge of the disk and provided with a member adapted to support it from the disk, a pinion fixed to the second shaft, a sector gear meshing with the last named pinion and provided with a thumb piece extending through said opening in the casing, a shaft for the sector gear, said shafts being arranged in alinement and the sector gear having a. slot for the reception of the first named shaft, and a spring secured to the casing and sector gear.

In testimony whereof I affix my signature.
